A CN original SCP, translated into english and permitted by the original author, ashauseall. Crtique all you like, please point out all those grammar mistakes. Dr Ablehouser gave me some help during the translation, Crayne gave me some initial feedback on #Site19, so here's a thank you to you two.

SCP-XXXX monitor unit located within Unit-28 and assigned field agents are to constantly…

This is sentence is awkward to read.

Description:

Your description doesn't actually tell us anything about your skip. What does it do? Why is it dangerous? Your Addenda has excerpts from these "work of truths" articles, but the only anomalous thing readily apparent is that the same vein of ideas are persistent across centuries.

Should the amount of people partially believing SCP-XXXX's contents becomes large enough, real life incidents matching its description will manifest.

This is silly. How many people are going to actually believe this "Truth of The World" skip? How many people does it take?

…recited the contents of an at-that-point uncontained SCP-XXXX instance manifesting in a story book to ██ preschool children…

That's all it takes? Two digits worth of people believing? That's an infinitesimally small percent of the population.

"Dangerous Level" of belief, ██ people reached "Sub-Dangerous Level"…

You should try to find better titles for these levels. "Dangerous Level" sounds cheesy.

The incident was thus resolved.

I don't think that this is necessary.

The Foundation is not certain whether SCP-XXXX is capable of reality-warping effects triggered by the meme, or [DATA EXPUNGED].

Currently, only 3 personnel, including the project director are permitted to view this document…

I thought everyone involved with this was E-Class?

after a cosmic fight.

Cosmic is not the correct word to describe a fight that took place on earth.

Final Opinion

This is a very long SCP. You could considerably tighten it up, and should. I don't dislike the idea, but there's a good amount of time just spent rambling. Be more concise on your containment procedures, make sure you put the anomalous effects of your skip in the description, and just condense the addenda.
